The purpose of the PPAP procedure is to document that development and validation of the part and the production process.
The benefits to the customer are that he receives in an organised manner all the information he needs and for the supplier that he knows what he is required to produce.
None of this prevents rejection of the PPAP. To ensure this one needs to manage the development in a proper manner and implement all the actions that are foreseen ion the planning mode.

OK,
Do you mean rejection of the Part in the future?
If so then your continual adherence to the approved process is what will ensure conformity of the part. This is true whether you supply PPAP or not.

my question was so because, my boss asked me we are doing ppap then why there is a rejection. his meaning was ppap should stop part rejections or we are failing to check/ review ppap properly OR we are not able to guide the supplier while submitting ppap.
hence i am confused. please elaborate on this

There are several reasons why parts are rejected even if you or your supplier has provided PPAP.
As we all know there is a gap between what we say and what we do. It is possible that the supplier is not acting as he said he would.
Another reason could be that not all the failure modes were seen in the FMEA and thus the controls are not in place to prevent or detect them.
Look at the non conformances and see if the reason why they occurred is because there was no control or the control was not effective.
This is why the FMEA should be updated when there has been a non conformance.
Does this help?

To also put in my two cents from what Howard said (which was awesome).
Purpose: To ensure process variables, variances, severity of occurrences, process validation, has been addressed and proofed. - to put in elementary terms.

Benefits: The same as purpose turned to a positive fashion. It ensures you can run a product at the best quality and delivery possible - to put in elementary terms again.

It will avoid rejections if you run an all automated system. There are still going to be variables you will not control. But if the severities are extreme you should take steps as a manufacturer to ensure you reduce the risk of failures to the point where you reduce those variables. And you have a corrective action process in place to try and prevent from happening again. This is all part of APQP and PPAP themselves.


REJECTIONS from PPAP: Sounds to me as if the DFMEA/PFMEA portion(s) of PPAP wasn't put together quite well in the Pre Production/QPQP - PPAP process. If you are seeing rejects then Failure Modes and Severities weren't addressed at a multifunctional arena or completed sufficiently?

I have great knowledge of PPAP and APQP, so please feel free to e-mail me and I can give more info and tools/examples to use. It's been a couple of years since I've done the automotive world but it's like riding a bike. Do you have specifics you are dealing with that I may help you with?

On a personal level I LOVE PPAP and APQP, it makes sense to me. I would use it more here if we weren't a job shop.

I'm a little late to the party on this one, but...

1. WHAT IS THE PURPOSE OF PPAP SUBMISSION

Here's what AIAG says, in the 3rd Edition PPAP manual:

The purpose of PPAP is to determine if all customer engineering design record and specification requirements are properly understood by the supplier and that the process has the potential to produce product consistently meeting these requirements during an actual production run at the quoted production rate.

2.WHAT ARE THE BENIFITS OF PPAP SUBMISSION TO SUPPLIER AND CUSTOMER

For the customer, see the response to #1 above. For the supplier, see the same. Note that the PPAP submission, and its underlying production run provide evidence of potential, not guarantees that nothing will ever go wrong. The PPAP package is a Kodak Moment--a "snapshot."

3.DOES IT AVOIDS REJECTION AT CUSTOMER END

No. Providing evidence of the ability to produce conforming product doesn't mean that product will always conform.

4.can anyone give quantifiable benifits

Yes, to at least the extent that it enables you to sell products to companies that require PPAP submissions.

Purpose of PPAP is to avoid Quality cost as well as DO the thing in organised manner

Thanks for valuable information.

I will app. that.

getting the things

As u say

Is it correct that PPAP & APQP reduces reduction?

If it is right mail me tools & procedure required for that.
